MARINE TRANSFER APPARATUS.

Application filed March 31, 1921.

To all whom it may concern:

Be it known that I, Gnoncn ARTHUR MIOKELSON, a citizen of the UnitedStates,

and a resident of the city of Vancouver, in the Province of BritishColumbia, Canada, have invented certain new and useful Improvements inMarine Transfer Apparatus, of which the following is a specification.

My invention relates to improvements in marine transfer apparatus,andthe object of my invention is to provide an apparatus of this naturewhich has a wide range of utility and which is cap-able of beingemployed with great facility in the unloading of cargoes carried inbarges, scows, or other vessels,

enabling such work to be carried out expeditiously and with greatconvenience so that discharging and transferring operations are effectedwith the maximum economy and efficiency. 7

I attain this object by the construction illustrated in the accompanyingdrawings in which Fig. 1 is a side elevation of the apparatus.

Fig. 2 is a sectional end view taken through the line 2-2 of Fig. 1showing method of transferring cargo from a scow or barge.

Fig. 3 is an end view showing method of discharging on to wharf.

Fig. 4 is a detail view of the hinge construction at the lower end ofthe elevating conveyor.

Figs. 5 and 6 'aredetail views showing 35 method of detachablyconnecting the transverse conveyor.

Similar figures of reference indicate similar parts throughout theseveral views.

1 indicates a floating structure, of scow formation, on which areerected towards each end bridge like structures, indicated generally bythe numerals 2 and 3, consisting of braced side columns 4 5 and 67respectively connected together at their upper 45 ends by longitudinalmembers 8 and 9 and transverse members 10and 11, and pivotally connectedat their lower ends to suitable brackets 12 secured to, the columns 4-5and 67 are booms 13 the upper ends of which are maintained in anyposition to which they may be raised or lowered by lines or falls 14.v15 indicates, a donkey engine and 16 a boiler therefor, while 17indicates a suitably mounted shaft provided with a bevel gear Serial No.457,316.

meshing with a bevel gear 19 secured to a vertical shaft 20, and whichshaft is rotated by the gear 19.

The shaft 20 is square and extends upwardly the full height of thestructure, belng rotatably supported at its upper end by any suitablemeans, and it passes freely through a block 21 capable of being raisedor lowered by means of a cable 22, one end of the cable being secured tothe block while its free end is passed over a sheave 23 and carried tothe donkey engine 15. Vertically slidable on the shaft 20 and rotatablyconnected thereto by a sliding key is a bevel gear 2 1 which meshes witha gear 25 secured to the head end shaft of an inclined conveyor 26arranged longitudinally of the structure 1 and the gear 24 is supportedon the block 21 so that lowering or raising the block also lowers orraises the gear 241, maintains both gears 24 and 25 in mesh, and alsolowers or raises the head end of the conveyor 26 when required.

27 indicates a cross conveyor the head end of which is supported on avertically movable block 28 in a position to receive discharge ofmaterial from the conveyor 26, and the block 28 may be raised or loweredto raise or lower the head end vof the conveyor 27 by means of a cableone end of which is secured to the block while its opposite end is ledto the engine 15. The length of the conveyor 27 is such that it canextend on to a wharf, indicated by the numeral 28*, when the structure 1is brought alongside same, its outer end being preferably supported on aroller 29, and for the manipulation of this conveyor booms 30 areprovided, these booms being pivotally connected at their lower ends tothe side columns 5 and suitably guyed at their upper ends so that theymay be used for other purposes besides the manipulation of the conveyor.

The lower end of the conveyor 26 is supported on the deck of the scow 1towards the end thereof and connected to it by a link arrangement,indicated by the numeral 31, is the head end of a longitudinal outwardlyextending conveyor 32 the tail end of which is supported by means ofsuitable tackle 33 hung from the upper end of a boom 34 pivotallyconnected at its lower end to. the side column 6, the tacklebeingoperated as re" through said block, a gear on the conveyor head endshaft, a bevel gear rotatably connected to said vertical shaftvertically slidable thereon and meshing with the said head end shaftgear, said bevel gear being supported on said block, and a cableconnected at one end to said block and at its opposite end to a powermachine.

3. A marine transfer apparatus comprising, a floating structure, aninclined conveyor mounted longitudinally thereon having its tail endclose to the deck of the structure and its head end elevated to above awharf level, a substantially horizontal conveyor the head end of whichis link- I connected to the tail end of the inclined conveyor, its tailend extending outboard from the structure, and means for carrying up thesaid tail end.

4:. A marine transfer apparatus comprising, a floating structure, aninclined con-' veyor mounted longitudinally thereon having its tail endclose to the deck of the structure and its head end elevated to above awharf level, a substantially horizontal conveyor extending outboard fromthe structure the head end of which is link-connected to the tail end ofthe inclined conveyor whereby it may be superposed thereon, a shaftrotatably mounted on one side of said horizontal conveyor and extendinglongitudinally of the same, and a gear rotatably connected to said shaftslidably mounted thereon.

5. A marine transfer apparatus comprising, a floating structure, aninclined conveyor mounted longitudinally thereon having its tail endclose to the deck of the structure and its head end elevated to above awharf level, a substantially horizontal conveyor extending outboard fromthe structure the head end of which is link-connected to the tail end ofthe inclined conveyor whereby it may be superposed thereon, a shaftrotatably mounted on one side of said horizontal conveyor and extendinglongitudinally of the same, a gear rotatably connected to said shaftslidably mounted thereon, and a conveyor extending at right anglestosaid horizontal conveyor having its head end adapted to be detachablysupported on the said longitudinal shaft, said conveyor being providedon its head end shaft with a gear adapted to mesh with the said slidablegear.
